Bonneville Power Administration
Big Eddy-Knight Transmission Project
AGENCY: Bonneville Power Administration (BPA), Department of Energy
(DOE).
ACTION: Notice of Availability of Record of Decision (ROD).
-----------------------------------------------------------------------
SUMMARY: This notice announces the availability of the ROD to implement
the Big Eddy-Knight Transmission Project in Wasco County, Oregon and
Klickitat County, Washington. Construction of the Big Eddy-Knight
Transmission Project will accommodate long-term firm transmission
requests that BPA has received by increasing BPA's 500-kV transmission
capability to move power from the east side of the Cascade Mountains
(along the Oregon/Washington border) to load centers (such as Portland,
Oregon) on the west side of the Cascades and to major transmission
lines serving California.
As described in the Big Eddy-Knight Transmission Project Final
Environmental Impact Statement (EIS) (DOE/EIS-0421, July 2011), this
project consists primarily of constructing a new, approximately 28-
mile-long, 500-kilovolt (kV) transmission line and ancillary facilities
between BPA's existing Big Eddy Substation in The Dalles, Oregon, to a
proposed new Knight Substation that would be connected to an existing
BPA line about 4 miles northwest of Goldendale, Washington. For the
transmission line, BPA has decided to build East Alternative Option 3.
For the first 14 miles, the line will use double-circuit towers
(combining the new line and an existing line on one set of towers)
mostly on existing right-of-way. The remaining 14 miles of the new line
will be built with single-circuit towers in a newly-established 150-
foot wide transmission line right-of-way. BPA has also decided to build
the small (about 1 mile) realignment of the East Alternative on the
Oregon side of the Columbia River, as described in the final EIS. For
the proposed new Knight Substation, BPA has decided to build Knight
Substation on Site 1, which is on private property about 0.5 mile west
of Knight Road. For the fiber optic cable necessary for system
communications, BPA has decided to build the Loop Back Option, which
will string fiber optic cable on the new transmission towers from BPA's
Big Eddy Substation to the new Knight Substation and back again. The
project also includes new equipment at BPA's existing Big Eddy and
Wautoma substations. BPA will install about 134 new lattice-steel
transmission towers that will have an average span length between
towers of about 1,200 feet. The double-circuit towers that will be used
for the first 14 miles will range in height from about 170-250 feet
tall; the single-circuit towers that will be used for the last 14 miles
will be about 108-200 feet tall. The towers on either side of the
Columbia River will be about 407 feet tall on the Oregon side and 232
feet tall on the Washington side.
The conductor, fiber optic cable, and overhead ground wire for the
new transmission line will be placed on these towers, and counterpoise
(which takes any lightning charge from the overhead ground wire and
dissipates it into the earth) will be buried in the ground at select
towers. Marker balls will be placed on the overhead ground wire across
the Columbia River and bird diverters will be installed on overhead
ground wire at select locations. The towers on either side of the
Columbia River will have lighting for aircraft safety. Road
construction will include about 16 miles of new road, 9 miles of
temporary road, 13 miles of existing road improvements, and 62 culverts
in intermittent streams (many stream crossings will have more than 1
culvert). In addition, portions of county roads that will be used to
access the line route will be improved as necessary.
All mitigation measures identified in the EIS that are applicable
to the selected alternative are adopted.
